Fin O'Sullivan is a lovable mess. Her imaginary angel and demon offer terrible advice, her cab-driving gig leaves too much time to overthink, and love? She had it-until she messed it up. Now, she's stuck living with the one who got away, a daily reminder of everything she lost. Avoiding feelings was working (sort of), but when tension turns to possibility, Fin has to decide: keep hiding behind sarcasm and self-sabotage, or finally fight for the love that's been right in front of her all along. After all, second chances don't knock twice-especially when they're already in your house.
